Description

Technical Field

[0001] The utility model relates to the technical field of switch protection shells, in particular to a switch protection shell. Background Art

[0002] A switch is a network device used for forwarding electrical signals. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common switch is the Ethernet switch. Other common switches include telephone voice switches, fiber optic switches, etc.

[0003] However, in the prior art, since switches come in different sizes, some switches need to match corresponding shells when installing the shells. At the same time, the shells are mostly fixed by bolts and other parts. Therefore, the installation operation is cumbersome and has certain limitations. In addition, some switch shells are prone to collision or falling from heights when accidentally touched during transportation or use, which can easily cause damage to the switches installed inside. Therefore, a solution is needed. Utility Model Content
